With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.134272-64-3,N-(2-Aminoethyl)maleimide Hydrochloride,as a common compound, the synthetic route is as follows.
To a solution of NHS ester, 7a (5 mg, 4.82 muetaiotaomicron) and l-(2-aminoethyl)-lH-pyrrole- 2,5-dione hydrochloride (1.7 mg, 9.64 muiotaetaomicron) in anhydrous dichloromethane (200 mu) was added DIPEA (1.512 mu, 8.68 muiotaetaomicron) under nitrogen. The mixture was stirred at room temperature for 4 hours and then concentrated in vacuo. The resulting residue was purified by RP-HPLC (CI 8, CH3CN / H20). Fractions containing desired product were frozen and lyophilized to give maleimide, compound D7 (3.5 mg, 68% yield). LCMS = 4.61 min (15 min method). MS (m z): 1062.8 (M + 1)+., 134272-64-3
The synthetic route of 134272-64-3 has been constantly updated, and we look forward to future research findings.
